In the bilayer quantum Hall system, a spontaneously charge imbalance state appears at the ground energy level. Gap in the collective excitation energy makes it stable against decoherence in macroscopic level. This state behaves as a spin 1/2 representation of SU(2) and can be controlled by applying the interlayer voltage. We suggest this system can be regarded as a macroscopic realization of a qubit for a quantum computer.
